A motion guide device includes: a track member including a rolling member rolling surface; a movable member including a loaded rolling member rolling surface, and a rolling member return passage; a pair of cap members including a direction change passage connecting the loaded rolling member rolling surface and the rolling member return passage; and a plurality of rolling members arrayed in a rollable manner on a loaded rolling member rolling passage, the rolling member return passage, and a pair of the direction change passages, the loaded rolling member rolling passage being made up of the rolling member rolling surface and the loaded rolling member rolling surface. A gap between the rolling member and the direction change passage at a boundary portion X is formed so as to become smaller than a gap between the rolling member and the rolling member rolling surface at the boundary portion.

Motion guide device

End plate for motion guide device

The motion guide device includes a lubricant supply passage provided in at least one of a pair of cover members provided to a movable member and configured to supply lubricant to an endless circulation passage, in which the lubricant supply passage includes at least a first lubricant supply passage &#x3b1; formed to extend in a direction orthogonal to a longitudinal direction of the track member from at least one of a left side surface and a right side surface of the cover member, and a second lubricant supply passage &#x3b2; connected to the first lubricant supply passage &#x3b1;, and a passage shape in a place connected to the first lubricant supply passage &#x3b1; of the second lubricant supply passage &#x3b2; is configured as a diameter-expanded hollow section having a diameter more expanded than a passage shape of another place. Thus, a new form of a cover member is provided.

The motion guide device includes a track member in which a rolling member rolling surface is formed along a longitudinal direction thereof, a movable member which is reciprocally movable with a number of rolling members being interposed therebetween and which is provided with a loaded rolling member rolling surface constituting a loaded rolling member rolling path opposing to the rolling member rolling surface and a rolling member return path, and a lid member provided with a pair of direction changing paths for connecting both end portions of the loaded rolling member rolling path and the rolling member return path to thereby constitute an endless circulation path. Flange portions are formed to both end portions of the movable member in the reciprocally moving direction by means of insert molding, and the flange portions are provided with fitting portions formed to end portion sides of the movable member.

A motion guide device includes a plurality of rolling element guide members provided along the entire length of a rolling element rolling surface so as to guide the unloaded side of a plurality of rolling elements that perform a rolling movement under load between the rolling element rolling surface and a loaded rolling element rolling surface. The rolling element guide member includes a beam member an outer member including a rolling element guide surface for guiding the unloaded side of the rolling elements, and the beam member and the outer member are insert-molded. Such a structure provides the motion guide device including the rolling element guide member that enables low cost manufacturing of a complex shape and capability of secure installation and guidance of the rolling elements with no deflection and can be adapted for use in various types by optionally selecting a connecting means.

A motion device () includes a track rail (), a moving body (), a plurality of rolling elements () rolling in an endless circulation passage formed at the track rail () and the moving body (), a pair of lid bodies () attached to end surfaces of the moving body () in a movement direction thereof, and a connector cover body () disposed along a rolling element rolling surface () formed at the moving body () to cover a rolling element connector () connecting and holding the rolling elements (). The connector cover body () has a frame-shaped cover member () which is fixed to the pair of the lid bodies () to be integrally disposed at both ends of the rolling element rolling surface () in a width direction thereof.

Motion device

A rolling guide device is capable of facilitating smooth circulation of rolling elements in an endless circulation path, and enhancing the accuracy of motion of a moving member relative to a track member. The moving member includes: a main body member having load rolling surfaces and return paths for the rolling elements; direction change pipes incorporating inner direction change paths and having inner peripheral guide surfaces of outer direction change paths, respectively; and lid members each being mounted on the main body member and having outer peripheral guide surfaces of the outer direction change paths. The main body member has position reference holes formed therein so as to serve as position references for the direction change pipes, respectively, whereas the direction change pipes have positioning protrusions formed thereon so as to be press-fitted into the position reference holes, respectively. Further, the direction change pipes include rotation restriction protruding portions.

Rolling guide device

A rolling guide device is capable of preventing a scooping piece formed on a circulation path module from being deformed along with use over time, and enhancing the durability of the scooping piece, thereby achieving smooth motion of a moving member relative to a track member. A moving member includes: a main body member having load rolling surfaces and return paths for rolling elements; direction change pipes having formed therein inner direction change paths and having inner peripheral guide surfaces of outer direction change paths, respectively; and lid members each being mounted on the main body member and having outer peripheral guide surfaces of the outer direction change paths. Each of the direction change pipes includes: a first half circulation segment and a second half circulation segment; and a scooping portion for guiding the rolling elements into each of the inner direction change paths.

Rolling guidance device

A motion device includes a track rail, a moving body, rolling elements, fixing members each fixed to an end surface of the moving body, and rolling element circulation members arranged between the moving body and the fixing members. The rolling element circulation members each have a connection section connected to the moving body so as to be rotatable about a Y direction, and a pair of first outside surfaces. The fixing members each have accommodation sections to accommodate the rolling element circulation members, and a pair of first inside surfaces closely contact with the pair of first outside surfaces. The respective rolling element circulation members and the accommodation sections are provided at both sides of the track rail interposed there between.

A motion guide device including a track shaft having a rolling surface; a moving member movable along the track shaft; a first seal member in sliding contact with a surface of the track shaft to close a gap between the track shaft and the moving member; and a second seal member provided along the rolling surface of the track shaft and closes the gap between the track shaft and the moving member. The second seal member includes: a fixing substrate locked to the moving member; and a seal portion fixed to the fixing substrate along the rolling surface of the track shaft and includes a seal lip portion in sliding contact with the surface of the track shaft and an extended seal portion in close contact with the first seal member while being compressed by the first seal member when the first seal member is fixed to the moving member.
